RRH Benbecula
Remote Radar Head Benbecula or RRH Benbecula, is an air defence radar station operated by the Royal Air Force. It is located at Cleitreabhal a'Deas, from Lochmaddy on the isle of North Uist in the Outer Hebrides of Scotland. The radar site was previously known as RAF Benbecula, the name having previously been associated with an RAF airfield on the island of Benbecula (now known as Benbecula Airport) and a nearby weapons testing range (now known as MoD Hebrides). History Radar station Although Benbecula Airport is now a civilian airfield, a military presence remained and the RAF Benbecula name continued when a radar station was established. A control and reporting centre, part of the UK Air Surveillance And Control System (ASACS), was constructed at the airfield which linked it to RAF Buchan in Aberdeenshire. The station was downgraded in the late 1990s to a remote radar head and the RAF pulled-out of the main airfield site at Benbecula. Initially under the command and co ...

North Uist
North Uist ( gd, Uibhist a Tuath; sco, North Uise) is an island and community in the Outer Hebrides of Scotland. Etymology In Donald Munro's ''A Description of the Western Isles of Scotland Called Hybrides'' of 1549, North Uist, Benbecula and South Uist are described as one island of ''Ywst'' (Uist). Starting in the south of this 'island', he described the division between South Uist and Benbecula where "the end heirof the sea enters, and cuts the countrey be ebbing and flowing through it". Further north of Benbecula he described North Uist as "this countrey is called Kenehnache of Ywst, that is in Englishe, the north head of Ywst".''A Description of the Western Isles of Scotland Called Hybrides''; Monro, Donald, 1549 Some have taken the etymology of Uist from Old Norse, meaning "west", much like Westray in Orkney. Another speculated derivation of Uist from Old Norse is ', derived from ' meaning "an abode, dwelling, domicile". A Gaelic etymology is also possible, with ' meanin ...

Wind Farm
A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used Wind power, to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore. Many of the largest operational onshore wind farms are located in China, India, and the United States.

Radar Stations
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. The t ...

Buildings And Structures In The Outer Hebrides
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NATO Integrated Air Defense System
The NATO Integrated Air Defense System (short: NATINADS) is a command and control network combining radars and other facilities spread throughout the NATO alliance's air defence forces. It formed in the mid-1950s and became operational in 1962 as NADGE. It has been constantly upgraded since its formation, notably with the integration of Airborne Early Warning aircraft in the 1970s. The United Kingdom maintained its own network, but was fully integrated with the network since the introduction of the Linesman/Mediator network in the 1970s. Similarly, the German network maintained an independent nature through GEADGE. Development Development was approved by the NATO Military Committee in December 1955. The system was to be based on four air defense regions (ADRs) coordinated by SACEUR (Supreme Allied Commander Europe). Starting from 1956 early warning coverage was extended across Western Europe using 18 radar stations. This part of the system was completed by 1962. Linked to existin ...

List Of Royal Air Force Stations
The Royal Air Force (RAF) operates several stations throughout the United Kingdom and overseas. This includes front-line and training air bases, support, administrative and training stations with no flying activity, unmanned airfields used for training, intelligence gathering stations and an early warning radar network. The list also includes RAF stations operated by the United States Visiting Forces, former RAF stations now operated by defence contractor QinetiQ on behalf the Ministry of Defence (MOD) and air weapons ranges operated by the MOD. Overseas, the RAF operates airfields at four Permanent Joint Operating Bases (PJOBs) which are located in British Overseas Territories. RAF stations and MOD airfields in the UK Royal Air Force RAF front-line operations are centred on seven main operating bases (MOBs): * RAF Coningsby, RAF Marham and RAF Lossiemouth (Air Combat) * RAF Waddington ( Combat Intelligence, Surveillance Target Acquisition and Reconnaissance) * RAF ...

Linesman/Mediator
Linesman/Mediator was a dual-purpose civil and military radar network in the United Kingdom between the 1960s and 1984. The military side (Linesman) was replaced by the Improved United Kingdom Air Defence Ground Environment (IUKADGE), while the civilian side (Mediator) became the modern public-private National Air Traffic Services (NATS). In the 1950s, the Royal Air Force was installing a radar network known as ROTOR using war-era radars like Chain Home along with new command centres. A new radar, the AMES Type 80, replaced all of the ROTOR radars and command centres with a series of nine Master Control Radars and a number of associated secondary radars. While these installations were in progress in the early 1950s, Compagnie générale de la télégraphie sans fil, CSF introduced the carcinotron, which could output a radio signal at any desired frequency. This made it a very effective Radar jamming and deception, jamming system, and it appeared to render ground-based radars li ...

Improved United Kingdom Air Defence Ground Environment
The Improved United Kingdom Air Defence Ground Environment, normally shortened to either UKADGE or IUKADGE, was the Royal Air Force's (RAF) ground-controlled interception system covering the British Isles during the 1990s. It consisted of a number of ground-based radar sites, links to airborne early warning aircraft and Royal Navy ships, a telecommunications system to send digital data and voice communications on a protected network, and processing systems based on VAX-11/780 computers. The network ultimately contained a dozen long-range radars including four Marconi Martello, two General Electric TPS-592, and six Plessey AR-320. UKADGE was developed in response to concerns about its predecessor, Linesman/Mediator. Linesman started in the 1950s, when it was assumed that any air attack on the UK would be by hydrogen bomb so no effort was made to "harden" the radars or its main control centre as such effort would be futile. By the mid-1960s, with the Soviet Union reaching strategic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defence Evaluation And Research Agency
The Defence Evaluation and Research Agency (DERA) was a part of the UK Ministry of Defence (MoD) between 1995 and 2 July 2001. At the time it was the United Kingdom's largest science and technology organisation. It was regarded by its official history as 'a jewel in the crown' of both government and industry.Eds.

South Uist
South Uist ( gd, Uibhist a Deas, ; sco, Sooth Uist) is the second-largest island of the Outer Hebrides in Scotland. At the 2011 census, it had a usually resident population of 1,754: a decrease of 64 since 2001. The island, in common with the rest of the Hebrides, is one of the last remaining strongholds of the Gaelic language in Scotland. South Uist's inhabitants are known in Gaelic as ''Deasaich'' (Southerners). The population is about 90% Roman Catholic. The island is home to a nature reserve and a number of sites of archaeological interest, including the only location in the British Isles where prehistoric mummies have been found. In the northwest, there is a missile testing range. In 2006 South Uist, together with neighbouring Benbecula and Eriskay, was involved in Scotland's biggest-ever community land buyout by Stòras Uibhist. The group also owns the "biggest community wind farm in Scotland", Lochcarnan, on South Uist which opened in 2013. Geology In common with th ...
